oh no! 3O2 Dampner on a 351W ! (urgent)

Stang_ROTY · 06-21-2001, 07:13 AM

Yesterday I went to the shop where my motor is to see how things were going and to check the size of the damper (because I need a specific FMPP spacer to run the serpentine system with the FRPP damper). I was shocked to find out that, according to the part # on the damper and the FRPP catalogue, the FRPP damper that's on my block is a 50oz balance for a 302! Needless to say I'm a little worried. My question is, since the Scat stroker crank, SFI damper, SFI flywheel, etc. were pre-balanced at the machine shop before install do I need to dis-assmeble the motor and get the correct 28oz damper or should everything be o.k. since it has been pre-balanced?? Thanks in advance.

Found out the answer to my own question by calling FRPP. The guy told me that as long as it is a balanced rotating assembly, I won't have any problems. He also added that there is a good and bad way to balance rotating assemblies. The good way is to remove any necessary weight from the crank, not the flywheel or damper. The bad way is vice versa. I feel much better now. Now if I could only find a timing pointer I'd be all set.
